I know nobody's perfect and I'm not asking for perfection, but these bugs are pretty alarming? It seems like these supposed coreutils replacements are being written by people who don't know anything about Unix, and also didn't even bother looking at the GNU tools they are trying to replace. Or at least didn't have any curiosity about why the GNU tools work the way they do. Otherwise they might've wondered about why things operate on bytes and file descriptors instead of strings and paths.

I hate to armchair general, but I clicked on this article expecting subtle race conditions or tricky ambiguous corners of the POSIX standard, and instead found that it seems to be amateur hour in uutils.
